Abstract
Abstract An illuminated safety helmet incorporating a light panel that is capable of producing electroluminescence, and also, reflecting incident light that is independent of the electroluminescence function of the panel. The light panel is secured to the helmet so as to be visible to an observer, and a power source is secured to the helmet so as not to interfere with the wearing of the helmet. The power source is connected to the light panel, and a control switch may be provided to control the power directed from the power source to the light panel.
